Endpoint User Behavior Analytics (EUBA) Signals in Zero Trust Identity Solution

In a zero trust identity solution, EUBA provides critical behavioral and contextual signals that enable dynamic, risk-aware authentication and access control. Unlike traditional perimeter-based security models, EUBA enables continuous verification by generating nuanced signals about user interactions, system access, and potential anomalies.

Endpoint User Behavior Analytics (EUBA) Signals

The key value proposition is transforming identity management from a static, binary authentication process to a dynamic, context-rich risk assessment mechanism. EUBA signals allow organizations to make real-time, granular access decisions based on comprehensive behavioral insights.
